BACTERIAL PHYSIOLOGY
Filament formation
Jane Saunders
Paragraph 1 and extract of Paragraph 2:
The FtsZ protein is essential for bacterial cell division, and polymerizes into a ring structure that constricts when the cell divides. It is the prokaryotic homologue of eukaryotic tubulin^, and previous studies have shown that it can polymerize in a GTP^ -dependent manner similar to that of tubulin. Formation of the tubulin protofilament is known to involve interaction of the C-terminal domain (involving the T7 loop) of one subunit with the GTP-binding domain of another and, owing to the similarities between the two proteins, it has been assumed that FtsZ would polymerize in a similar manner.
Now, Jan Löwe and co-workers provide experimental evidence that FtsZ forms the same protofilament as tubulin.
